Installing CrashPlan on Linux

Available To:

  • Faculty (currently appointed) and Staff

How to Get:

Download the latest version of the CrashPlan Client from the downloads page.  When you click on the download link, you will be asked to authenticate with your NetID and Password. Enter your credentials and click OK.



After you have authenticated, you will be asked to open or save the file.  Select the Save File option and click OK.  The default save location will be your Downloads folder in most cases.



In your Downloads window in your browser you should see the completed download.  Right click on the finished file and select Open Location, Open File Location or Open Containing Folder depending on what browser you used to download the file. 



When you have opened the directory that has the installer archive, right click on the archive package and select the Extract Here option.



After you have extracted the archive package for the installer, please proceed to open a terminal window (example shown below).



In the terminal, change directory to the newly created folder and run the install script using the ./ command as super user or by using sudo ./ (depending on what Linux distribution you are using).



If Java Runtime Environment is not already installed on your machine the install script will offer to install it for you. If you are prompted to download and install JRE, type [Y] or just press Enter.



Press Enter at the following prompts to accept the default values for install paths. 



Once you have gone through all the pre-install prompts, you will be asked to review the selections you have made.  At this point choose [Y] or just press Enter.



Once the installation process is complete, the install script will report “CrashPlan has been installed and the Service has been started automatically. Press Enter to complete installation.” Press Enter.

You will see: "Your Linux system is currently configured to watch 8192 files in real time.  We recommend using a larger value; see the CrashPlan support site for details"

You will be asked if you would like to start CrashPlanDesktop. At this prompt select no by pressing n and then Enter

Then do either:

su nano /etc/sysctl.conf


sudo nano /etc/sysctl.conf


Add the following line at the end of the sysctl.conf file: 


Note: Other command line editors can be used instead of nano.


Reboot the computer.

If you are the technician who is installing CrashPlan for another user, allow that user to log in and continue the process from this point as the following steps will pertain to their user environment.  If you are the primary user for this computer, continue on by using your NetID and password when prompted.


Once the computer has rebooted, click the CrashPlan icon on the desktop to run CrashPlanDesktop and continue on with the setup process.
